Pfizer said Tuesday it plans to use data from a clinical trial it concluded last month to seek expanded approval of its RSV vaccine, Abrysvo, for all adults ages 18 and up. The vaccine maker also said it has begun trials for the drug in children ages 2-18.

Pfizer plans to use data from a clinical trial it concluded last month to ask regulators to expand approval of its respiratory syncytial virus (RSV) vaccine, Abrysvo, for all adults ages 18 and up, the drugmaker said in a press release Tuesday.

Pfizer also reported that it has begun a trial evaluating the drug in children ages 2-18 who are at higher risk for RSV disease.

Family medicine physician Dr. Kat Lindley told The Defender she is concerned about the rush to promote vaccines to treat RSV when the vaccines have serious risks and there are other methods of prevention and treatment.
